Ansible Venv Django CMS
Im making an ansible role to install a clean Django CMS instance, when trying to activate my installed Virtual Env I'm getting a permission error, I have read up that sometimes this can be caused when making the env with different permissions to when you try and activate it. I have tried with and without root sudo in both instances. I am using a Ubuntu/Trusty64 box. Here is the error im getting from my task: TASK [dependancies : Activate Venv] ******************************************** fatal: [default]: FAILED! => {"changed": false, "cmd": ". env/bin/activate", "failed": true, "msg": "[Errno 13] Permission denied", "rc": 13} Here is my role file: --- - name: Update apt-get become: yes apt: update_cache: yes - name: Install Packages apt: name: "{{ item }}" with_items: - nginx - python3 - python-pip - nodejs - git - python-passlib # for htpasswd - postgresql - libpq-dev # for postgresql - python-psycopg2 # for postgresql - ansible # to run ansible-pull become: yes - name: Install Python Libraries pip: name: "{{ item }}" executable: pip become: yes with_items: - virtualenv - awscli # for backups - name: Create Venv command: virtualenv env args: creates: env/bin/activate - name: Activate Venv command: . env/bin/activate - name: … -
accessing request object in a SessionWizardView in django
I am using a django forms SessionWizardView to implement a form wizard. The url configuration is as follows; url(r'^contact/(?P<pk>\d+)/$', views.ContactWizard.as_view([DummyForm, OtherForm]), name='contact'), The idea here is that I am passing a primary key so that I can populate the form with some initial data. The form is loaded from another view as follows: def populate_review_form(request): pk = 2 return redirect('contact', pk=pk) Here I am trying to pass a hard-coded primary key to the form. Now, my form implementation is simple where I am overriding the get_form_initial to generate the initial value for the form as follows: class ContactWizard(SessionWizardView): def get_template_names(self): return "test.html" def get_form_initial(self, step): pk = self.request.GET.get('pk') # Just attempt to print the primary key print pk, self.request.GET return {} def done(self, form_list, **kwargs): return HttpResponseRedirect('index') The issue is that this always prints None <QueryDict: {}>. So, basically my parameter is not being passed or I am unable to access the correct request object. Is it possible in Django to have this communication? -
Django - authenticate() A user with that username already exists
Okay I'm confused. I'm trying to build a login page, but whenever I try to login, django gives the error that the username already exists. I haven't used save() anywhere. I'm using authenticate(), I referred the Django docs for that: https://docs.djangoproject.com/en/1.10/topics/auth/default/#how-to-log-a-user-in Here is my code, please tell me where I'm going wrong: forms.py class LoginForm(forms.ModelForm): username = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Username'})) password = forms.CharField(widget=forms.PasswordInput(attrs={'placeholder': 'Password'})) class Meta: model = User fields = ['username', 'password'] views.py class LoginFormView(View): form_class = LoginForm template_name = 'login.html' # display a blank form def get(self, request): form = self.form_class(None) return render(request, self.template_name, {'form': form}) # authenticate user def post(self, request): form = self.form_class(request.POST) if form.is_valid(): username = form.cleaned_data['username'] password = form.cleaned_data['password'] user = authenticate(username=username, password=password) if user is not None: if user.is_active: login(request, user) return redirect('slrtcebook:home') return render(request, self.template_name, {'form': form}) login.html <div class="form-container"> <form method="post" enctype="multipart/form-data"> {% csrf_token %} {% for field in form %} {{ field }} {{ field.errors }} {% endfor %} <input id="submit" type="submit" value="Log in" /> </form> </div> <p>Don't have an account? <a href="/">Register here</a></p> -

How I can connect two variables of the same model?
I'm doing an app in Django witch a form that evaluate a candidate for a job vacancy. The form must have a candidate(ok), a valuer(ok) and a variable wich the criteria and a score for this criteria. So I create a model with this attributes(Avaliacao) to use it in the forms.py - this model connect the criteria(Criterio), the valuer(auth.user),the candidate (Candidato) and the attribute to receive the score for the criteria (nota).

The model Candidato receive the dates of the candidate: name, e-mail, link for Github/Linkedin and etc, and it is used in another form (registration form). Well let me show you: forms.py: from .models import Candidato, Avaliacao#, Aval from django import forms class CandForm(forms.ModelForm): class Meta: model = Candidato fields = ('name', 'e_mail', 'github', 'linkedin', 'Ensino_superior','cover_letter') class AvalForm(forms.ModelForm): class Meta: model = Avaliacao fields = ('criterio','candidato','avaliador','nota') models.py: from django.db import models from jsonfield import JSONField from site_.settings import MEDIA_ROOT class Criterio(models.Model): label = models.CharField(max_length=100) def __str__(self): return self.label class Candidato(models.Model): name = models.CharField(max_length=100) e_mail … -

Get country code by coordinates using django gis

As you understand it take many requests, so how can I get the country code of the coordinates using Django gis? -

How to migrate data from foreign key in unmanaged model to managed model in Django 1.7?
We're slowly moving from unmanaged to managed models, one foreign key at a time. The current situation: class OldOrg(Model): pass class Meta: managed = False class OldService(Model): offered_by = models.ForeignKey(OldOrg) class Meta: managed = False class NewOrg(Model): org = models.OneToOneKey(OldOrg) class NewService(Model): service = OneToOneKey(OldService) The next step: class NewService(Model): service = OneToOneKey(OldService) offered_by = models.ForeignKey(NewOrg) The problem happens in the data migration using django's inbuilt migration system. The field OldService.offered_by does not exist, so we cannot use that to get to the NewOrg primary key for use in NewService.offered_by. # This works in the shell but not in a migration for ns in NewService.objects.all(): ns.offered_by = ns.service.offered_by.new_org In the migration, OldService doesn't have the field offered_by_id either. Is there some other way to get at the data in OldService? -

How to register Django models that are only used in tests
I'm writing an app that has a custom model field. I want to test that field, using a model that is only used within tests, but I'm struggling to get the model working in tests. Some of my app structure is like this: myapp/ fields.py models.py tests/ fields/ models.py tests.py settings.py tests/fields/models.py is like this: from django.db import models from myapp.fields import MyCustomField class MyTestModel(models.Model): custom_field = MyCustomField() I then import MyTestModel and try to use it in tests/fields/tests.py. Things I've tried... 1. Initially I got: RuntimeError: Model class tests.fields.models.MyTestModel doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS. 2. So I added "tests", to INSTALLED_APPS in tests/settings.py. But then I get: django.db.utils.OperationalError: no such table: tests_mytestmodel 3.

Django Rest Framework with nginx caching requests
Since I started using DRF with nginx/gunicorn server I've noticed that queries are being cached somehow. I.e. I got 10 records of object A in database (Postrgres) - if I ask for them with GET, I got 10 - ok. But then, when I add another record, I got 10 instead of 11 (although I see 10 in database). I have to manually reset gunicorn to get the correct result, which is not how REST should work... Here's my nginx config (tried some cache settings): upstream myapp{ server unix:/var/django/gunicorn.socket fail_timeout=0; } server { listen 80; server_name myapp.example.com; client_max_body_size 4G; access_log /var/django/myapp/logs/nginx-access.log; error_log /var/django/myapp/logs/nginx-error.log; # DRF API below location /api { expires off; add_header Cache-Control "private, no-cache, must-revalidate, max-age=0"; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_connect_timeout 75s; proxy_read_timeout 300s; proxy_pass http://myapp; } # JS for webapp (backbone) location / { alias /var/django/myapp_web/; } } and gunicorn as well: #!/bin/bash NAME="myapp" DJANGODIR=/var/django/myapp SOCKFILE=/var/django/gunicorn.socket USER=appuser GROUP=appuser NUM_WORKERS=5 DJANGO_SETTINGS_MODULE=myapp.settings DJANGO_WSGI_MODULE=myapp.wsgi TIMEOUT=300 echo "Starting $NAME as `whoami`" cd $DJANGODIR source /var/django/myapp/bin/activate export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE export PYTHONPATH=$DJANGODIR:$PYTHONPATH RUNDIR=$(dirname $SOCKFILE) test -d $RUNDIR || mkdir -p $RUNDIR exec /var/django/myapp_venv/bin/gunicorn ${DJANGO_WSGI_MODULE}:application \ --name $NAME \ --workers $NUM_WORKERS \ --reload \ --timeout $TIMEOUT \ --user=$USER --group=$GROUP \ --bind=unix:$SOCKFILE \ --log-level=debug … -
